Hello! I'm new to this site. I've owned an 87 RX and a 95 Legacy L Wagon. Anyway, I'm buying an 89 RX today. Only thing is, it had the driver's side camshaft seize. I'm no mechanic, and I don't know much about Subarus yet, but I was wondering if someone could direct me to a thread that would be relevant to fixing this or maybe just throw some information at me. Thank you and thanks for having me! )
